Frits, I guess you are right, there is more to this discovery than we might think. If this is what I think it is, then there will also be some VERY interested fourstroke customers, ones that might race in GP class! I can see why you NEED to keep a lid on it.

Youthful over exuberance i guess.

Attachment 312774 Youthful over exuberance ..... too right, or something!!!

That bloody quote was over threes years ago.

I am a slow reader too, just catching up ...

Got an update from Neels, now turbulent works fine.

Newb question:
When using the numbers I got from turbulent, can I play around with ignition timing in prescribed mode, or do I have to run turbulent again everytime I change timing for a rpm point?

No, once you have saved and imported the turbulent combustion model, you can use that with changed timing numbers, saving it as a new file each time.

What about the peak and overev power - the main/corrector system can hves just as much effect there as in the mid.

Only a part of the rev range shown. The whole range including overrev will show the total effect of the changes.

Very nice.I'll put that on my todo list.

I need to get my O2 sensor working consistently to do the top end. I was basically just trying to get the bottom end better as the 5 speed MX gearbox is not the best for the track.

My EGT only shows 950 at max power on the track so I still have some work to do. I'm hope the EGT is correct ? Ashburton's dyno shows close to 12.5:1 fuel air so I'm not sure why the temp is so low.

Maybe I need to do a bench calibration of the sensor and GPX Pro box. .
